To re-roof with solar panels, you need to install the solar system first, then place new roofing materials around it. Solar roofing is growing fast because it saves money on energy bills while protecting your home. According to PRNewswire, solar roofing demand is growing 15% annually. Many homeowners add solar panels during a roof replacement to save time and money. The average payback period for solar roofs is 6 years in Hawaii and 16 years in Washington. A federal tax credit covers 30% of the installation cost through 2032.
What Comes First, Solar or Roof?
You should install solar panels before new roofing materials. This lets roofers work around the panels without removing them. Solar panels need to sit on a solid, stable roof base to work safely.
The process takes more time than a normal roof replacement. Roofers must coordinate with solar installers. According to IBISWorld, 80% of roofing activity now focuses on renovation and replacement projects.

How Much Does Solar Re-roofing Cost?
Solar re-roofing costs more than regular roofing. According to RubyHome, the average roof replacement cost is $9,526, with a range of $5,868 to $13,217. Solar panels add $15,000 to $25,000 on top of that.
The good news? Roof replacement ROI can reach 110% during home resale, according to the NAR Remodeling Impact Report 2025. Solar adds extra value because buyers see long-term energy savings. You can split costs over time with financing options.
Material Options for Solar Roofs
You have several roofing material choices when adding solar:
| Material Type | Cost Per Sq. Ft. | Lifespan |
|---|---|---|
| Asphalt shingles | $4.25-$4.95 | 20-30 years |
| Metal roofing | $5.50-$17.05 | 40-80 years |
| Rubber/flat roofing | $5.50-$7.50 | 40-50 years |
| Concrete tiles | $11.00-$19.80 | 100+ years |
Metal roofing works best with solar panels. Metal lasts 40 to 80 years, which matches solar panel lifespans. South-facing roofs are optimal for energy production in the U.S.
Key Steps for Solar Re-roofing
First, get a roof inspection. Check for damage or weak spots. Next, install solar panels before new roofing materials go down.
Then roofers place new shingles or metal panels around the solar system. Finally, the solar company reconnects the system to your electrical panel. According to the National Association of Home Builders, the average U.S. roof size is 2,647 square feet. Plan for solar and roofing work to take 2 to 4 weeks total.
